Benefits of technology

[0007] Exemplary embodiments of the present invention provide a display device including a sound unit having a small size, a light weight structure, and an improved sound quality.
[0008] Exemplary embodiments of the present invention provide a polarizing film assembly capable of improving a sound quality.
[0016] According to exemplary embodiments of the present invention, the display device having the speaker film generates the sound. Therefore, the size and thickness of the display device may be decreased.

Problems solved by technology

When a size and a weight of the magnetic speaker are decreased to have a lighter weight and a smaller size, a sound quality of the magnetic speaker is deteriorated.

Abstract

A polarizing film assembly includes a polarizing film, a speaker film, a vibration improving layer, and a line member. The polarizing film includes a polarization layer transmitting a light vibrating in a polarizing direction. The speaker film is on the polarizing film to change an electric signal into a mechanical vibration to generate a sound. The vibration improving layer is interposed between the polarizing film and the speaker film to improve the mechanical vibration. The line member is electrically connected to the speaker film to transmit the electric signal. Therefore, a size and thickness of a display device are decreased while maintaining sound quality of the display device.

Description

[0001] The present application claims priorities to Korean Patent Application No. 2005-65293, filed on Jul. 19, 2005, and Korean Patent Application No. 2005-65299, filed on Jul. 19, 2005, and all the benefits accruing therefrom under 35 U.S.C. §119, and the contents of which in their entireties are herein incorporated by reference.
